The assessment of major obstacles to community integration which may result from an acquired brain injury (ABI) is needed for rational planning and effective management of ABI patients' social adjustment. Currently, such a generally acceptable measure is not available for the Italian population. This paper reports the translation process, the internal consistency, and the inter-rater reliability data for the Italian version of the Mayo-Portland Adaptability Inventory-4 (MPAI-4), a useful measure with highly developed and well documented psychometric properties. The MPAI-4 is specifically designed to assess socially relevant aspects of physical status and cognitive-behavioural competence following ABI. It is a 29-item inventory which is divided into three subdomains (Abilities, Adjustment, and Participation indices) covering a reasonably representative range
Twenty ABI patients with at least one-year discharge from the rehabilitation facilities were submitted to the Italian MPAI-4. They were independently rated by two different rehabilitation professionals and a family member/significant other serving as informant (SO). Internal consistency was assessed by calculating the Cronbach's alpha values. Inter-rater agreement for individual items was statistically examined by determining the interclass correlation coefficient (ICC).
In addition to the 8% of perfectly correspondent sentences, a clear prevalence (75.5%) of minor semantic variations and formal variations with no semantic value at the sentence-to-sentence matching was found. Full-scale Cronbach's alpha was 0.951 and 0.947 for the two professionals (rater #1 and rater #2, respectively), and was 0.957 for the family member serving as informant (rater #3). Full-Scale ICC (2.1) between professionals and SOs was 0.804 (CI=95%; lower-upper bound=0.688-0.901).
The Italian MPAI-4 shares many psychometric features with the original English version, demonstrates both good internal consistency and good inter-rater reliability. The MPAI-4 confirms to be suitable for research applications in postacute settings as an efficient, broad and inclusive outcome measure for adult subjects with ABI.
评估因获得性脑损伤（ABI）而导致的社区融合的主要障碍，这对于合理规划和有效管理 ABI 患者的社会适应能力是必要的。目前，意大利人群中还没有一种普遍接受的此类评估方法。本文报告了 Mayo-Portland 适应能力量表-4（MPAI-4）的意大利版本的翻译过程、内部一致性和评分者间信度数据，该量表是一种有用的工具，具有高度发达和记录完善的心理测量学特性。MPAI-4 专门用于评估 ABI 后与身体状况和认知行为能力相关的社会相关方面。它是一个由 29 个项目组成的量表，分为三个子领域（能力、调整和参与指数），涵盖了相当有代表性的范围。
20 名 ABI 患者在康复机构出院后至少一年接受了意大利版的 MPAI-4。他们由两名不同的康复专业人员和一名家庭成员/重要他人（SO）作为信息提供者进行独立评分。内部一致性通过计算 Cronbach's alpha 值进行评估。通过确定组内相关系数（ICC），对个体项目的评分者间一致性进行统计学检验。
除了 8%的句子完全对应外，还发现了明显的小语义变化和形式变化，而句子之间的语义值没有变化。两位专业人员（评分者 #1 和评分者 #2）的全量表 Cronbach's alpha 值分别为 0.951 和 0.947，而家庭成员作为信息提供者（评分者 #3）的全量表 Cronbach's alpha 值为 0.957。专业人员和 SO 之间的全量表 ICC（2.1）为 0.804（置信区间=95%；下限-上限=0.688-0.901）。
意大利版的 MPAI-4 与原版英语版有许多心理测量学特征，具有良好的内部一致性和评分者间信度。MPAI-4 适合在康复后环境中进行研究应用，是一种用于评估 ABI 成年患者的高效、广泛和全面的结果测量工具。
